Ethereum (ETH) coin pairs represent trading combinations between Ethereum and another cryptocurrency or fiat currency. Common pairs include ETH/BTC (Bitcoin), ETH/USDT (Tether), and ETH/USD (US Dollar). These pairs allow users to exchange Ethereum for other assets on crypto exchanges. ETH/stablecoin pairs like ETH/USDT are popular for managing price volatility, while ETH/altcoin pairs (e.g., ETH/BNB or ETH/SOL) are useful for crypto diversification. Coin pairs are essential for price discovery and liquidity in the market. Traders use them to speculate, hedge, or convert between assets. Ethereum’s wide adoption ensures it’s paired with nearly all major cryptocurrencies and stablecoins.
